修改方式
- 配置类
- 配置文件
配置类
- 增加配置类：配置类必须拥有 @Configuration 且不能在 @ComponentScan 包下
package com.learning.springcloud.config;
import com.alibaba.cloud.nacos.ribbon.NacosRule;
import com.netflix.loadbalancer.IRule;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class RibbonConfig {/** * 全局设置负载均衡策略 * * @return */ @Bean public IRule iRule() {return new NacosRule(); }}- 增加客户端负载配置 @RibbonClients
package com.learning.springcloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.netflix.ribbon.RibbonClient;
import org.springframework.cloud.netflix.ribbon.RibbonClients;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
@SpringBootApplication
@RibbonClients(value = {@RibbonClient(name = "stock-service", configuration = com.learning.springcloud.config.RibbonConfig.class)
})
public class OrderApplication {public static void main(String[] args) {SpringApplication.run(OrderApplication.class); }@Bean @LoadBalanced public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) {return restTemplateBuilder.build(); }
}配置文件
-
注释启动类上 @RibbonClien
-
applicaiton.yml 中增加 对应服务的个性化负载均衡策略
